My present invention is concerned with gravity -flow systems and has a preferred aplplication in association with pressure lubrieating systems, more particularly for delivering lubricant b y gravity ii'ow from a pressure line to the bearing or bearings ot a such swivel or other connection.

The invention is shown embodied in the steering knuckle ota motor vehicle and pro- Tides convenient means for reliably supplying with clean oil, all or any number oi' the bearings carried by or associated with said knuckle and without the need for selective finanipulation by direct manual access to the lindividual bearings and without the use of any protruding or projecting conduits likely to be torn loose in ordinary use ot the vehicle.

Where a downwardly extending pipe line delivers by gravity flow, for instance, to the .tie rod bearings ot a steering knuckle, ir-

regularity of operation might be encoun- .tercd by the lubricant admitted thereto be-k ing arrested in the pipe until after several .lubricating operations, a column of suiiicient weight had accumulated therein, to flow out, so that the bearing would intermittently receive an ovorsupply ot oil stored in the.

pipe in several intervening operations,

Where two or more bearings at different levels, for instance, the drag link and the tie y from Vreceiving too little oil.

Accordingl to the present invention, such defective operations, both the liow arresting and the siphoning Vactions noted, are obviated by venting preferably the upper part oit' anyA training conduit devoid of a lubri cant trap, so that even though said conduit vsystem be of diameterk as little as /S or even lg bore, lubricant admitted thereto `would flow out to the bearing at the lower Serial No. 485,056.

end thereof, substantially without time lag, this because atmospheric pressure is main tained both at the upper and'lower end of such conduit.

Since a vent indiscriminately located or formed in a knuckle would be subject to clogging by dust or mud splashed onto the knuckle in usev of the vehicle, it is an object of the invention to arrange the vent 'to vsubstantially preclude such clogging, without, however, forming it so large that foreign particles could Without clogging the. vent pass therethrough to the conduits. Y

F or this purpose, the vent is disposed in a. particularly protected position and is, moreover, arranged to inherently shed any mud ordirt that might reach it.

ln one application, the upper ot the swivel bearings for the knuckle permits the free passage of lubricant to the top of the king pin from the corresponding inlet fitting carried by a rcontiguous part on the axle and .conduits carried by the knuckle and kin ,flow

intercepting relationship with respect to lubricant that has traversed the swivel lead -to the knuckle bearings. Venting is effected vthrough a bore leading to atmosphere from the region Vof the upper end of the king pin,

said bore ext-ending in a downward direction through the structureand substantially protected by the brake shield or some other .part of the knuckle or axle, or carried by the knuckle or the axle.

vIn the` accompanying drawing in which is shown one embodiment of the invention,

vFig. 1 is aside elevation rpartly in section oi one embodiment of the invention, and

Fig. 2 is a fragmentary detail sectional view taken on line 2-2 of Fig. 1 showing a modification.

Referring now to Figs. 1 and 2 of the drawing. I have shown a knuckle assembly comprising an axle beam 10 havingaking pin 11 extending through an eye 12 thereof, `protruding therebeyond andadording bearings ing 14 has a plug 18 Vpressftitted into its lower .end .to prevent escape of lubricant, a screw plug 19 closing an aperture therein through which a pin may be driven for removing the king pin in disassembly. A ball thrust bearing 16 rests on the lower knuckle clevis jaw 17 and sustains the axle beam thereupon The knuckle has rigidly secured thereto an arm 20 which in this instance is curved and which has at the outer end thereof an up- Awardly extending ball stud 21 taper-fitted thereinto, as shown, by pressure applied by a nut 21 threaded on the end of the stud and pressing against the arm. Intermediate the ends of the arm 20 is a ball stud 22 for the tie rod, said stud extending downward therefrom, and also taper-fitted by pressure applied by nut 22.

According to the p resent embodiment, there are lubricated from a single source both the upper and lower bearings of the king pin in their respective bushings, the ball thrust bearing 16 upon which the axle beam rests, the drag link bearing and the tie rod bearing.l To this end, the lubricant is delivered to the knuckle through a pressure-tight pipe 24 kwhich may be of seamless metal having an out1et-termina125 which may be a drip, plug,

for instance, of the type disclosed in the copending application of Edward H.y Kocher, Serial No. 22,104, filed April 10th, 1925. The dri plug 25 is fitted into a downwardly exten ing socket 26 in a cap structure 27- rigid with the axle. The king pinis provided with a reduced upper extension 28, protruding into` a tightly fitting central Vaperture in cap 27I which is preferably also pinned to the king.

pin. The cap is generally annular in con-` struction except for the lug attachment of the.

drip plug and encircles the upper end of the knuckle, An annular washer 29 is interposed between the knuckle and; the cap to., preclude the entry of dust to the. swiveling or bearing surface, i The lubricant from the drip plug passes through a bore 3() in the cap plugged at its outer end at 31 and drips downwardly through a bore 32 in an annular pilot dange 33 on the cap fitting into the upper knuckle clevis. The lubricant collects in the annular Well 34, the bottom of which is formed by the upper end of the bushing 13 and the shoulder 35 at the base of the reduced king pin extension 28. The upper bushing is provided with a passageway, preferably formed by a plurality of longitudinal external grooves 36, which communicate with a peripheral groove 37 intermediate the ends of said bushing. The groove 37, in turn, communicates with a pipe 38 fitting at its upper end in a corresponding apertured boss 39 formed integral with the upper knuckle bearing extending downwardly from substantially the level of groove 37 along the structure of the knuckle to the drag link bearing.

The pipe 38 is shown of relatively large diameter, one-quarter inch bore, or more, so that the lubricant can trickle downwardly past any air therein, said larger diameter part extending down at least to the level of the out# let 139 to the drag link bearing. The rest of the pipe 40 which may extend, as shown, along the drag link below outlet 139, may be of smaller diameter, too small to permit passing of lubricant around any air therein, in manner and for reasons fully set forth in my patents above identified; Preferably the outlet end of the line 40 extends radially ins ward at the eye 41 at which the ball stud 21 is mounted, and delivers by way of a radial bore 42 in the stud into an axial bore 43 plugged at 44 at its upper end and communicating through one or more of the radial outlet bores 16.9 through the ball for oiling the corresponding drag link bearing.

rlhe king pin has a flat 45 near its upper end determining a narrow passage communieating with the well 34 and a radial bore 46 The king pin has a radial bore`4j8 establishing` communication between the axial bore 47 and a peripheral groove 49 about the king pin, substantially at the level of the ball thrust bearing from which the latter is lubricated` The thrust bearing is constructed so that. lubricant may drain therefrom to supply the tie rod bearing. The assembled bearing is enclosed in a sheet metal capsule composed oftwoy telescoped caps, the lower of which 50 rests in the knuckle and carries a star washer 51 upon which the thrust bearing assembly rests, the axle beam resting on the upper cap 52. Such lubricant as overfiows around the ball bearing passes between the teeth of the star washerthrough one or more apertures 50 in the cap 50, into an annular groove 53 formed in the upper surface of the lowerV knuckle clevis jaw, which drains into a vertical bore 54 through t-he lower jaw of the clevis, said bore being plugged at 55 at its lower end. Bore 54 delivers between its ends into a pipe 56 secured by an appropriate terminal 57 to the knuckle, said pipe extending downward to eye 58 in the arm 20 which carries the tie rod ball stud 22. The latter is bored in the same manner as the drag link .stud to supply lubricant to the tie rod bearing.

In the present embodiment, the bore 47 of the king pin and the pipe 56 leading to the tie rod both are made of diameter too small to permit passing of lubricant about any air therein, and if desired, as small as ffy bore. To facilitate free flow of the lubricant through the small conduit and to preclude stoppage of a plurality of charges therein followed by flooding of the bearing, the upper end of the knuckle is vented. In one en ibodilnent, this vent consists of a bore 158 extending obliquely downward through the upper knuckle from the side wall of the well IIS "34 and communicating with a shallow downwardly sloping groove 59 at the wheel side ,of the knuckle at which the brake shield GO or equivalent structure is secured. I have thus disposed a vent Where dust and dirt will not readily get at it, and even if they should, would drop therefrom by gravity.

yThe king 'pin bore 47 and the communicating tie rod conduit 56 are effectively vented through a radial bore 61 which connects said king pin bore with the vented well 34.

In operation, lubricant admitted to the knuckle from a remote source of pressure will be yforced through the drip plug and will iiovv through the passage -32 into the well 34 where it divides. One part of the lubricant will pass along longitudinal grooves 36 tothe peripheral groove whence it escapes through the boss 39 and pipe 38 to the drag link bearing 21 by way of pipe 40 and bores 42, 43 and 169. Normally lubricant will be trapped in the pipe below the level of the drag link outlet bores 39 and it will be understood that such lubricant as passes down the large pipe 38 on to the trapped lubricant, will cause the delivery of a corresponding charge f at the bearing.

Another part of the lubricant from the well 34 will fiow down the fiat 45 through the bore 46 into the longitudinal bore 47 of the Aking pin. Said bore being vented through the radial bore 61, well 34 and venting aperture 158, the lubricant will readily pass down therethrough and through radial bore 48 into the yball thrust bearing 16. A small part of the lubricant will pass downward from the groove 49 along the lower king pin bearing 14 to lubricate the latter, the lubricant collect-ing between the plug 18 and the bottom of the king pin. kOil escaping from the ball xthrust bearing passes between teeth of the Y star washer 51 through the ports 50 to the n from the upper king pin bearing to the drag link or from the latter to the lower king pin bearing is substantially precluded.

In Fig. 2 is shown a modification of the embodiment shown in Fig. 1 in which the venting b'ore in the upperknuckle clevis eX- tends preferably obliquely at 62 but .partly through. the thickness of the upper knuckle and thence communicates with a longitudinal borek 6.3 terminating at the lower face of said clevis `jaw. Inasmuch as the thrust bearing i `16 is at the lower end of the axle eye, a small kspace will be maintained between the upper face of -th'eaXle eye 1Q andthe upper clevis jaw, so that the bore v63 is effectively vented thereat. K

While I have shown the invention applied to a reverse Elliott type aXle,that is, to one,v in which the clevis lon the knuckle `straddles the axle, yit will be understood that the general'principles thereof may be readily applied to an Elliott aXle, in which the elevis is on the axle landstraddles the knuckle eye.

The invention vis not limited in'its applicationto remote control lubrication or to the use of 'a drip plug for admitting lubricant to the knuckle. An oil cup or other lubricant admitting fitting may be applied to the knuckle instead ofthe drip plug, for supplying the various knuckle `bearingsin the vmanner disclosed and claimed.

This application is a division of application Serial No. 51,7 33, iiledAugust 22, 1925.

It is to beunderstood that there may be many changes and vmodifications made in the construction and the arrangement of the details of my invention without departing from the scope thereof, and I intend to include all such variations as fall within the 'scope of the appended claims in this application, in which only the preferred forms of my invention havebeen disclosed. 1
